Given the importance of social integration and participation in inclusive settings for young children with autism spectrum disorder (ASD), the purpose of this systematic review was to examine instructional outcomes and participant, teacher, group, and instructional characteristics that may be pertinent to successful group instruction for young…

Objective: Search strategies are essential for the adequate retrieval of studies in a systematic review (SR). Our objective was to identify problems in the design and reporting of search strategies in a sample of new Cochrane SRs first published in The Cochrane Library in 2015. Study design and setting: We took a random sample of 70 new Cochrane…

Criteria for suitable research designs for use with large databases are suggested and analyzed. The advantages and disadvantages of several types of quasi-experimental designs are compared. Examples are taken from the authors' research with data from the Manitoba Health Services Commission. (Author/AL)

Twenty-nine steps necessary for data file preparation for secondary analysis are discussed. Data base characteristics and planned use vary the complexity of the preparation. Required techniques (file verification, sample verification, file merger, data aggregation, file modification, and variable controls) and seven associated pitfalls are defined…

A project conducted in Tennessee from 1984 through 1989, Student Teacher Achievement Ratio (Project STAR), serves as a context for a discussion of educational research. The decisions required in major research projects and the problems in carrying out research are seldom discussed in conferences that present research results as completed efforts.…

Statewide assessment data available from two school years, two grade levels, and five sources (achievement tests; student, principal, and teacher questionnaires; and principal interviews), were aggregated to more closely investigate the relationship between student/school characteristics and student achievement. To organize this large number of…

This document is intended as a resource guide for institutional researchers, based on the experience of the Johnson County Community College (Kansas) Institutional Research Office. It includes pragmatic suggestions concerning research design and research problems which are incorporated into discussions of research questions, reporting data,…

This overview of the research process for the novice information retrieval (IR) researcher provides guidance on selecting a research question, choosing the type of test, defining variables, developing or using databases, finding and processing queries, assigning treatments to experimental units, collecting and analyzing the data, and presenting…

The movement toward integration of qualitative and quantitative research methods within the same study has been most evident in social policy research. Four major approaches to integrating can be identified in recent studies. The sequential, the parallel, and the fused models have been rather widely used. The interactive model, developed during…

In 1959, the American Institutes for Research (AIR) and the University of Pittsburgh selected a stratified random probability sample of all secondary schools (public, parochial, and private) in the United States, tested all their students in grades 9-12 with a two-day battery of aptitude tests, information tests, tests of ability and achievement,…

Because of various flaws in their design, most research studies that have up to now examined the transition of youth to the work setting have failed to pinpoint ways of improving existing programs. Many of these design flaws (including lack of a uniform set of outcome measures, failure to routinely incorporate control groups, and failure to design…
